UTP 86 FN-5 cast iron
Classifications graphite-basic coated FeNi stick electrode
EN ISO 1071 AWS A 5.15
E C NiFe-1 3 E NiFe-CI
Characteristics and field of use
UTP 86 FN-5 was developed for high-quality production and construction welds of cast iron
with nodular graphite (spheroidal cast iron). Dissimilar joints with steel are possible. It is
mainly used in production welding of ferritic spheroidal cast iron with specific mechanical
properties, such as EN-GJS-400-18-LT
The used NiFe-bibllic core wire gives the stick electrode a high current carrying capacity
and a good deb rate. Good wetting characteristics0n cast iron are achieved by the
stable arc and smooth flow. The deposit is highly crack resistant with good strength and
toughness. Machining is possible.

Welding instruction
Prior to welding, clean the weld area, remove casting skin and check for any cracks. Hold
the electrode vertically and keep a short arc. Large parts can be preheated to 80°C. For the
purpose of stress relieving, it is recommended to peen the deposit directly after welding.
